Abstract: A system and method for connectivity-aware assignment of volumes among the storage controllers of a storage system is provided. In some embodiments, during a discovery phase, a connectivity metric is determined from a device discovery command. The connectivity metric is recorded into a data structure that identifies a plurality of hosts and a plurality of storage controllers of a storage system. In response to the determining of the connectivity metric, a storage controller ownership of a first volume is changed to improve connectivity between a host of the plurality of hosts and the first volume. In some such embodiments, a storage controller ownership of a second volume is changed to balance load among the plurality of storage controllers, and the discovery phase is, in part, a response to the change in the storage controller ownership of the second volume.
